US12601081 - Devices, systems, and methods for treatment of tubulars

Disclosed herein are devices, methods, and systems for applying a coating and/or a plating to a surface, including metal surfaces on tubulars or gun barrels. In at least one embodiment, a device includes a rod and an applicator that is rotatable around the rod. The applicator includes a base on which are fixedly attached one or more arms. At one end of the arms is attached one or more applicator pads, which contain the coating and/or plating to be attached to a surface. In a further embodiment, a novel ablative coating includes an electroplated nanostructured porous metal layer combined with embedded nanoparticles. The porous metal layer may include zinc (Zn) and nickel (Ni), and/or alloys thereof. The embedded nanoparticles may include titanium dioxide (TiO 2 ) and hexagonal Boron Nitride (hBN), which are anti-corrosion, friction-reducing, and/or thermally insulating.

This patent describes a device for applying coatings to surfaces, particularly for metal tubulars or gun barrels, featuring a rotatable applicator with pads that contain the coating material. The device includes a rod, a base, arms, and a spring mechanism, allowing for efficient application of a novel ablative coating that incorporates anti-corrosion and friction-reducing properties.

Claim 1

1 . A device for applying a coating to a surface, the device comprising: a rod; an applicator rotatable around the rod, the applicator comprising: a base, one or more arms extending away from the base, each of the one or more arms having a first end and a second end, and one or more applicator pads comprising a coating to be applied to a surface; a spring extending vertically upwards from a top surface of the base; and a screw connected to the spring, wherein the first end of the one or more arms is attached to the base, and wherein the second end of the one or more arms is attached to the one or more applicator pads. a rod; an applicator rotatable around the rod, the applicator comprising: a base, one or more arms extending away from the base, each of the one or more arms having a first end and a second end, and one or more applicator pads comprising a coating to be applied to a surface; a base, one or more arms extending away from the base, each of the one or more arms having a first end and a second end, and one or more applicator pads comprising a coating to be applied to a surface; a spring extending vertically upwards from a top surface of the base; and a screw connected to the spring, wherein the first end of the one or more arms is attached to the base, and wherein the second end of the one or more arms is attached to the one or more applicator pads.
